We demonstrate reconfigurable, all-optical, two-channel demultiplexing (DEMUX) based on a dispersion asymmetric NOLM using a single baseband control pulse. Switchable operation between two-channel and single-channel DEMUX is also achieved. Error-free 40-to-10 Gb/s DEMUX is obtained.
Three provisioning schemes are proposed to effectively establish lightpath requests in multi bit-rate transparent networks affected by XPM. The scheme exploiting a novel GMPLS extension, by limiting the use of worst-case penalties, significantly improves the overall blocking performance.
We propose and demonstrate a novel NRZ-DPSK-WDM system which can simultaneously demultiplex and demodulate multiple-wavelengths using single commercial AWG for rates between 10 and 40 Gb/s. BER results after transmission show the practicality of the system.
10 G can be groomed into 40 G channels or transmitted natively, reducing reach of concurrently mixed 40 G channels. For long-term migration under traffic growth, optimal network cost is achieved by early investments in 40 G-only transmission systems.
We introduce a new routing method, 10-40 Gb/s synergy, that reduces the blocking probability of at least 15% against classical routing with both bit-rates. The transmission estimator enables better performance.
A detailed theoretical model of the high bit rate operation of a vertically gain-clamped semiconductor optical amplifier with high bit rate return-to-zero and non-return-to-zero input signals is presented. It is shown that good eye opening at 10-40 GBit/s can be achieved at sufficiently high operating currents (hundreds of mA in a realistic construction). A resonance between the relaxation oscillations...
As PMD compensation has become a very intense subject of research in recent years, the achievement of simple PMD compensators based on a feedback signal is a key issue. As PMD compensation uses a feedback indicator for system performance evaluation, such feedback signals must reproduce the DGD variations with time. In this paper, the correlation between DGD and different feedback signals is studied...
